Patent DE-2740990-A1 (DE)
Title: Two speed motor for automatic washing machine - has composite rotor comprising two concentric core rings with short circuited induction motor winding in outer ring
Inventor: HAVERKAMP HANS
IPC: H02K1/26
Filed: 1977-09-12
Abstract: The two speed motor functions as an induction machine at low speed and as a commutator motor at high speed. The four pole induction motor rotor comprises a core ring (7) with a two phase short circuited bar winding (10). This fits over a core cylinder (8) carrying the windings (12) for the commutator motor rotor. Using separate cores gives greater freedom of slot number choise to suit the particular winding. The core material (13) under the outer winding (10) provides a path for the induction motor flux and thus greatly limits the parasitic retarding torques generated in the commutator winding.
Patent DE-2742517-A1 (DE)
IPC: B30B9/22
Filed: 1977-09-21
Abstract: In a press, the internal space of the container (1) is divided by a shroud-shaped skin (8) into a pressure space (11) and a compression space (10). The pressure space (11) is provided with an inlet arrangement (13, 14) for a pressure fluid, and the compression space (10) is provided with an arrangement for withdrawing liquid (16, 17). To keep the solids away from the openings (17) with which the compression space (10) is provided, and to prevent blocking of these openings, the openings are covered with a filter material (50). This measure increases the collecting area of each opening and has the result that the time required for separating the liquid from the solids is reduced. The apparatus is used mainly for extracting the juice of fruits. <IMAGE>

Title: Filter with integral spray nozzle cleaning system - using water to move the nozzles backwards and forwards along the filter
Inventor: COLOMER PIERRE
IPC: B01D46/00
Filed: 1978-01-07
Abstract: A filter with an integral cleaning system is described. The washing system comprises spray nozzles on a tube connected to the water supply. The tube with the nozzles is moved on a carriage to and fro along the length of the filter, being supported on a horizontal rail parallel with the top of the filter case. The traction is provided by means of a hydraulic motor which is integrated with the cleaning fluid circuit. The motor may either be stationary and linked to the movable carriage by means of a chain transmission or may itself be mounted on the carriage. The system eliminates the use of an electric motor and the electric circuitry necessary to produce the directional changes needed at each end of the rail. This means that the difficulties of operating an electric motor so close to spraying nozzles and the periodic maintenance necessary to an electric motor are removed.

Title: Odorous and offensive vapour treatment - by spraying with water and oxidising agent after removing condensable constituents
Inventor: VRIES EGBERT DE
IPC: B01D53/34
Filed: 1978-03-29
Abstract: Vapours contg. offensive or foul smelling constituents from organic sulphides, amines, aldehydes, ketones, alcohols etc. are treated by passing through a condensing zone to remove condensible constituents, and spray treating uncondensed vapours. Spray treatment is by (a) passing uncondensed vapours into the upper region of a spray zone, (b) introducing a finely divided spray of water and oxidising agent, droplet size up to 10 mu, into the upper region of the zone, (c) allowing the droplets to fall unimpeded through the zone for >=20 seconds removing the offensive and foul smelling constituents, and (d) separately removing treated vapour and settled out spray liq from the lower part of the zone. The process uses lightweight component elements and has lower power requirements, e.g. a fan of only 10 horsepower is sufficient for a vapour flow of 1100 ft/3min. It is economical and its physical location is flexible e.g. it can be roof mounted.

Title: High pressure liq. pump - has flexible hose with one end fixed and other moved by reciprocating plunger to vary curvature of hose
Inventor: ROMETSCH JOHANN
IPC: F04B43/08
Filed: 1978-09-30
Abstract: A flexible semicircular hose (2) is held at one end in a block. This contains a non return inlet valve (4) into the hose. The other end of the hose is held in a reciprocating plunger (8). This has a non-return discharge valve (10) into a discharge connection (11). The plunger is depressed against a spring by a cam or eccentric (9) on a camshaft. The movement of the plunger bends the flexible hose and thus alters its cross section and therefore volume. This gives a pumping action on the fluid in it. The stroke can be adjusted by a linkage (17, 15) which alters the rest position of the plunger.

Title: Receiver circuit for radio or TV appts. - produces automatic frequency control voltage independently of interference pulses and has capacitive diode tuning
Inventor: THIELE WERNER
IPC: H03J7/08
Filed: 1978-12-07
Abstract: The receiver circuit has the control voltage held by an RC circuit with large time constant after tuning to a transmitter frequency. This RC circuit is disconnected during tuning. The capacitor (9) in the RC circuit is charged to a voltage roughly equal to the control voltage during tuning. This voltage appears at the output of the automatic frequency control loop (5) after the oscillator has been tuned to the transmitter frequency. The RC circuit is switched in slowly via a continuously variable impedance, whilst its disconnection is fast. Connection and disconnection are accomplished via a FET (24) controlled by the voltage across the capacitor. By suppressing interference, affecting the control voltage, the received sound or picture are prevented from adverse effects. The tuning voltage for the capacitive diodes of oscillator circuits is changed by superimposition via a control circuit independence on frequency-dependent control circuit.
